The similarity between the blood cells and stomach cells is ; Both help maintain homeostasis ( B )
The stomach cells helps in the storage of food ,enzyme secretion and digestion of food substance consumed. this way they help to maintain the acidity and water level in the body through the process of food digestion and enzyme/acid secretion.
The blood cells transports oxygen from the lungs to the tissues where they are needed and also taking back CO₂ from the tissues to the lungs. the blood cells also carries the necessary nutrients from the digested food to the various tissues. this way the blood cells help to maintain homeostasis in the body.
Hence we can conclude that the similarity between the blood cells and stomach cells is ; Both help maintain homeostasis
